The story of Dan Marlowe, a pulp writer who suffered from amnesia, befriended an ex-con, and later inspired writers like Stephen King:
“Physicians thought the amnesia was psychosomatic, brought on by stress and money troubles, but there were hints of physical problems too. Before his brain emptied out, Marlowe had been laid low by crushing migraines, and there was evidence he’d had similar problems during his youth. In time, Marlowe would tell people the memory loss resulted from a stroke, and the symptoms he described (weakness on his left side, for instance) seemed to bear that out.
“In any case, his creative-writing ability vanished, and his life fast-reversed 20 years. He was trapped in a noir plot eerily similar to that of Never Live Twice, the 1964 Marlowe thriller in which amnesia blanks out the mind of government operative Jackrabbit Smith, who has to fight his way back to his old life, blasting bad guys and spanking a woman psychologist along the way.”
